A half inch beam torque wrench most likely would be FOOT POUNDS, rather than INCH POUNDS.
For sure you don't want to mix them up.
My inch pound torque wrench is 3/8" drive. They also come in 1/4" drive.
If you have an inch pound torque wrench in 1/2" drive, it may have such a high reading that it might not be accurate or it might be hard to make out something like 10 inch pounds.
